Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173806, here are decompositions:

23 + 173783 = 173806
29 + 173777 = 173806
107 + 173699 = 173806
137 + 173669 = 173806
233 + 173573 = 173806
257 + 173549 = 173806
263 + 173543 = 173806
449 + 173357 = 173806

Showing the first eight; more decompositions exist.
